So when it determines that people can marry in the same sex or to their animals,,it will be OK?
OK is a value judgement. That is an individual determination that can only be legitimately made by an individual. If the society as a whole determines that is what the majority have decided, then that will be what they have decided. A minority, or the reps of the majority do not have the right, or the priviledge to make any such decision.
If everyone else determines marriage is "OK" between any human and a pig, I will disagree and have, maintain and exercise the right to openly disagree.
